Abstract

Augmented reality (AR) is a highly interdisciplinary field which has
received increasing attention since late 90s. Basically, it consists
of a combination of the real scene viewed by a user and a
computer generated image, running in real time. So, AR allows
the user to see the real world supplemented, in general, with
some information considered as useful, enhancing the user’s
perception and knowledge of the environment.
In this paper, a hand-based interface for mobile AR applications is
described. It detects the user hand with a pointing gesture in
images from a camera placed on a head-mounted display worn by
the user, and it returns the position in the image where the tip of
the index finger is pointing at. Our approach is based on skin
color, without the need of glove or colored marks.
